“…Composting can effectively degrade residual antibiotics in organic fertilizers but not completely remove them. The possible reason was that the antibiotic residue decayed significantly in the manure after the treatment, resulting in decreased antibiotic residue [29]. Previous studies showed that the target antibiotics were removed, while the proliferation of ARGs could not be prevented, and there is a significant positive correlation between the residues of antibiotics at subtherapeutic levels and the accumulation of ARGs [53], and that their degradation also has a positive effect on maintaining the presence of ARGs [54].…”

“…Approximately 100 mg of organic fertilizer samples was used to determine their C, H, O, N, and S contents and C/N ratios by means of an elemental analyzer (vario MACRO cube, Elementar, Germany) [28]. The antibiotic residues were determined by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS, Thermo Fisher Scientific, Waltham, USA) analysis, and extraction and purification procedures followed the description by Qian et al [29,30] Nine different antibiotics were analyzed: SDZ, SMZ, SMN, OTC, TC, CTC, Dox, Oflox, and Enroflox. In this experiment, according to the parameters of the test instrument, the detection limit was in the range of 0.5-15 µg kg −1 manure (dry weight), and the limit of quantification was in the range of 1.5-50 µg kg −1 manure (dry weight) [29].…”

Organic fertilizer is a major carrier that stores and transmits antibiotic resistance genes (ARGs). In the environment, due to the application of organic fertilizers in agriculture, the increasing diversity and abundance of ARGs poses a potential threat to human health and environmental safety. In this paper, the microbial community structure and ARGs in different types of organic fertilizer treated with composting were examined. We found that the abundance and diversity of ARGs in earthworm cast organic fertilizer were the lowest and the highest in chicken manure organic fertilizer. Interestingly, the abundance and diversity of ARGs, especially beta-lactam resistance genes, sulfonamide resistance genes, and macrolide-lincosamide-streptogramin B (MLSB) resistance genes, in organic fertilizers were reduced significantly, while composting caused no significant change in mobile genetic elements (MGEs), where antibiotic deactivation and the use of efflux pumps were the two most dominant mechanisms. It was clear that removal of ARGs became more efficient with increasing reduction in the bacterial abundances and diversity of potential ARG hosts, and integron-mediated horizontal gene transfers (HGTs) played an important role in the proliferation of most ARG types. Therefore, the reduction in ARGs was mainly driven by changes in bacterial community composition caused by composting. Furthermore, rather than HGTs, the diversity and abundance of bacterial communities affected by compost physical and chemical properties were the main drivers shaping and altering the abundance and diversity of ARGs, which was indicated by a correlation analysis of these properties, antibiotic residues, microbial community structure, and ARGs. In general, high-temperature composting effectively removed antibiotic residues and ARGs from these organic fertilizers; however, it cannot prevent the proliferation of MGEs. The insights gained from these results may be of assistance in the safe and rational use of organic fertilizers by indicating the changes in microbial community structure and ARGs in different types of organic fertilizer treated with composting.

“…A study of the Austrian territory manure revealed that the concentration of chlortetracycline and sulfadiazine were 46 mg/kg and 91 mg/kg from swine manure, respectively [8]. These contaminants may enter soils via direct manure application as organic fertilizers, before their subsequent phyto-uptake by crops [9]. Furthermore, it may increase the chances of transferring antibiotic-resistant bacteria into humans as a result of the consumption of crops contaminated with antibiotics and estrogen [10,11].…”

“…The effects of the stirring rate, volume, and modes of H 2 O 2 dosage on the estrogenic and antibiotic removal efficacy were assessed. Moreover, the concomitant removal of estrogens and antibiotic, plus their physicochemical values under optimum reaction conditions in different livestock manures, were Catalysts 2019, 9,644 3 of 14 determined. The results can highlight a useful and convenient method that is suitable for the safe treatment of manures contaminated with estrogens and antibiotics.…”

The presence of estrogens and antibiotics in animal manure has raised considerable attention regarding their potential risks in both the soil system and human health. This study investigated the removal of estrogens (estriol (E3), bisphenol A (BPA), estradiol (17β-E2), ethinyl estradiol (EE2)), and antibiotic (sulfadimethoxine (SDM)) in livestock manure using the Fenton oxidation process. Based on the removal efficiency of estrogens and antibiotics, the optimal conditions of the Fenton oxidation process were as follows: an H 2 O 2 dosage of 10.5 mmol/g slurry, an Fe 2+ /H 2 O 2 molar ratio of 0.067 mol/mol, a stirring rate of 100 rpm, the feeding of an identical amount of H 2 O 2 in two steps (at 0 and 15 min), a manure/reactor ratio of 1:25, and a reaction time of 100 min. Under these conditions, the removal efficiencies of E3, BPA, 17β-E2, EE2, and SDM in cow manure were 72.1%, 88.2%, 89.4%, 73.3%, and 99.7%, respectively. In the above-mentioned optimal conditions, the simultaneous removal of estrogens and antibiotic in different manure conditions led to the removal of above 70% of targeted contaminants, except for E3 in swine and chicken manure in all the manure. The findings demonstrate the useful application of the Fenton oxidation process in the concomitant removal of antibiotics and estrogens from animal manure, which reduces the associated risks to human health and environmental safety.

“…The indiscriminate use of antibiotics in animal husbandry, especially in pig farms, has become a gateway for these pollutants into the environment (NGUYEN et al, 2017). Antibiotics may be used for different purposes, from the therapeutic and/or preventive use in the treatment of diseases, such as infections, diarrhea, or even as growth promoters (CHENG et al, 2019;BEN et al, 2017;TASHO;CHO, 2016;GUO et al, 2016;QIAN et al, 2016a). Several authors (CHENG et al, 2019;TASHO;CHO, 2016;GUO et al, 2016;GELBAND et al, 2015;DAGHRIR;DROGUI, 2013;DU;LIU, 2012), indicate that, on average, 60% of the veterinary drug administered to the animals is excreted through urine and feces (PULICHARLA et al, 2017), and the most commonly used group of drugs is antibiotics (TASHO; CHO, 2016.…”

The increasing need for animal protein has exerted pressures on the current animal production system. One of the alternatives found by producers to improve animal performance has been the use of veterinary drugs, especially antibiotics. However, its indiscriminate use can be a risk to the environmental balance of the producing locations since Brazil has approximately 42 million pigs. With this herd, pig farming represents a great potential for generating environmental impacts. As an alternative use of the large volume of liquid pig manure generated, many producers have been using this slurry in the soil as a bio fertilizer. Residues of veterinary drugs are capable of accumulation with environmental matrices and leach into water resources. In this sense, it is mandatory to dedicate more efforts on the study of techniques and processes for the treatment of organic effluents contaminated by veterinary drugs. Low-cost and environmentally friendly alternative treatment systems are necessary, in order to minimize the entry of these contaminants into the environment. Therefore, the composting process, defined as aerobic microbial decomposition process of organic matter, can be an alternative for treating the effluents contaminated by veterinary drugs. This review to aims to create awareness in the academic community regarding the veterinary drug residues and their contamination potential in different environmental matrices, as well as evaluating the composting process as a technique to minimize the impacts of the swine activity waste on the environment.
